Substitute Part Grouping Explanation

The 93C86C-I/MS qualifies as a direct substitute for the 93C86CT-I/MS based on the following criteria:

Identical Electrical Parameters:

• Memory capacity: 16Kbit
• Memory organization: 2K x 8, 1K x 16
• Interface protocol: Microwire serial interface
• Clock frequency: 3 MHz
• Write cycle time: 2ms
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C

Identical Physical Parameters:

• Package type: 8-MSOP
• Package dimensions: 0.118", 3.00mm Width
• Mounting type: Surface Mount
• Base product number: 93C86

Difference in Packaging Format: The primary distinction between these parts is the distribution packaging: the main part (93C86CT-I/MS) is supplied in Tape & Reel format, while the substitute (93C86C-I/MS) is supplied in Tube format. Both parts are manufactured by Microchip Technology and share identical device specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 93C86CT-I/MS and 93C86C-I/MS are active production parts from Microchip Technology with identical functional specifications and package dimensions. Selection between these parts should be based on the following factors:

RoHS Compliance Consideration: The 93C86CT-I/MS carries ROHS3 compliance certification, making it suitable for applications subject to RoHS directives. The 93C86C-I/MS is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Packaging Format: The 93C86CT-I/MS is supplied in Tape & Reel format, optimized for automated assembly processes. The 93C86C-I/MS is supplied in Tube format, suitable for manual handling or lower-volume applications.

Inventory Availability: The 93C86C-I/MS has higher current stock availability (1654 units) compared to the 93C86CT-I/MS (1072 units).

Both parts are electrically and mechanically interchangeable when installed on the same PCB layout, as they share identical pin configurations, electrical characteristics, and thermal specifications.

Frequently Asked Questions (FAQ)

Q: Can the 93C86C-I/MS replace the 93C86CT-I/MS in production assembly?

A: Yes, from an electrical and mechanical standpoint. The primary consideration is packaging format: the 93C86CT-I/MS in Tape & Reel is optimized for automated pick-and-place assembly, while the 93C86C-I/MS in Tube format requires manual handling. Additionally, if RoHS compliance is mandated, the 93C86CT-I/MS must be used.

Q: What are the key parameters that define substitutability for this part?

A: Substitutability is determined by: memory capacity (16Kbit), memory organization (2K x 8 or 1K x 16), interface protocol (Microwire), clock frequency (3 MHz), supply voltage range (4.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and package type (8-MSOP with identical pin configuration and dimensions).

Q: Are there any functional differences between these two parts?

A: No. Both parts are manufactured by Microchip Technology and have identical electrical specifications, memory organization, interface characteristics, and thermal performance. The only differences are packaging format and RoHS compliance status.

Q: What is the significance of the packaging format difference?

A: Tape & Reel packaging is designed for high-volume automated assembly with pick-and-place equipment. Tube packaging is used for lower-volume applications or manual assembly processes. The choice depends on production methodology and volume requirements, not on electrical performance.

Q: Does the RoHS non-compliance of the 93C86C-I/MS affect its electrical performance?

A: No. RoHS compliance status relates to material composition and environmental regulations, not to electrical functionality or performance characteristics. Selection should be based on regulatory requirements for the end application.
